HOUSING FOR ELECTRIC INCANDESGENT LAMPS.

App1ication filed May 3,

T 0 all whom it may concern:

Be it known that we, FLOYD C. SMITH, and ROBERT STOFFEL, citizens of the United States, and residents of Syracuse, in the county of Onondaga and State of New York, have invented a certain new. and useful Housing for Electric Incandescent Lamps, of'which the following is a specification.

This invention has for its object the production of a particularly simple, eflicient and rugged housing for electric incandescent lamps and it consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a side elevation of this housing for electric incandescent lamps.

Figure 2 is an elevation, partly in section, looking to the left in Fig. 1.

Figure 3 is a plan view thereof.

This housing for incandescent electric lamps comprises a hollow tubular box or body having its ends closed and means on its top wall for supporting the lamp, the body having a light projecting opening in its side wall and also a door in its side large enough to permit the insertion and removal of a lamp socket into the body and also large enough to permit the insertion and removal of a lamp.

1 designates the body which is cylindrical in general form and closed at its lower end by a wall 2 integral with the body and closed at its upper end by a cover 3 discoidal in general form and having means as a depending threaded nipple 4 for supporting a lamp socket and means as an internally threaded nipple 5 for connection to a support, as a conduit enclosing the service wires or a bushing suspended from a cord composed of the service wires.

The cover is secured in position in any suitable manner as by screws 6 extending therethrough and threading into internal lugs 7 in the upper end of the body.

The body is provided between its ends with a light projecting opening here shown as circular in form and preferably with an integral tubular projection 8 extending from 1919. Serial No. 294,558.

the opening to direct the light upon the objects as gages in locomotives, etc.

The body is also formed with a door opening in the side thereof diametrically opposite the light projecting opening and with a door 9 closing said door opening. The door 9 has the same curvature as the body and is provided with a marginal bead 1O lapping the margin of the body around the door bpening. Said door is preferably hinged at both of its side edges and the hinges are constructed to act as latches so that the hinge at either edge can be unlatched and the door swung on the hinge at the other edge.

As here illustrated thedoor and body are provided at each side edge of the door 9 with upper and lower pairs of lugs 11, 12, and 13, 14, having alined perforations; the door is formed at each side edge with a barrel 15 located between and spaced apart from the pair of lugs 11, 12, and 13, 14, the barrel being in line with said lugs; and spring pressed pins 16, 17 are carried by the barrel and are pressed by their springs 18 outwardly axially through the alined perforations of the pairs of lugs 11, 12, 13, 14.

The pins 16, 17 are provided with laterally extending handles 19, 20 by means of which the pins can be withdrawn from the lugs 12 and 14 for the purpose of opening the door gs the hinge at the opposite side edge of the c oor.

By pinching the handles 19, 20 toward each other the pins can be withdrawn from the lugs 12 and 14 and the door opened, and when closing the door the handles 19, 20 are pinched toward each other in order to permit the pins to pass into alinement with the lugs 12 and 14 on the box.

The housing is particularly adapted for use in places where it is subject to hard knocks as in locomotive cabs, and the like, and owing to its construction it can withstand hard usage, it directs the light where required, and it permits the lamps to be readily replaced.

What we claim is:

An incandescent electric lamp housing for electric conduit systems, comprising a cylindrical box or body open at one end and having an integral wall closing the other end and also having an elongated door opening in its cylindrical Wall for the removal and replacement of the lamp, said opening terminating short of the upper and lower ends of the cylindrical Wall, and a door for said opening following the contour of the cylindrical wall, the Wall being also formed with a light projecting opening in its cylindrical Wall, a closure for the open end of the body said closure having means for connection in an electrical conduit and a lamp socket car- 10 of Onondaga, and State of New York,-this 15 1919.
